Abstract

It is intended to provide a filter filtration material which comprises a polytetrafluoroethylene (PTFE) porous membrane and has secured rigidity by integration of the porous membrane and a breathable support material. The filter filtration material is excellent in breathability and joinability of respective layers constituting the filtration material. In the filter filtration material, the breathable support material comprises a breathable substrate and a fiber layer located on the substrate such that it comes into contact with the PTFE porous membrane, and has a structure in which the substrate and the fiber layer are joined to each other by allowing fiber of the fiber layer to penetrate inside the substrate and entangling it with the substrate, and the fiber layer contains polyolefin-containing fiber joined to the PTFE porous membrane.
